Look up the new HTML5 Input Types. These instruct browsers to perform client-side filtering of data, but the implementation is incomplete across different browsers. The pattern attribute will do regex-style filtering, but, again, browsers don’t fully (or at all) support it. However, these won’t block the input itself, it will simply prevent submitting the form … Read more
If you are using numpy: >>> import numpy as np >>> a = np.arange(8) >>> mask = np.array([False, False, False, False, True, True, True, False], dtype=np.bool) >>> a[mask] array([4, 5, 6]) If you are not using numpy you are looking for itertools.compress >>> from itertools import compress >>> a = range(8) >>> mask = [False, … Read more
If there’s a mask in your model, it’ll be propagated layer-by-layer and eventually applied to the loss. So if you’re padding and masking the sequences in a correct way, the loss on the padding placeholders would be ignored. Some Details: It’s a bit involved to explain the whole process, so I’ll just break it down … Read more
It’s a portable way to set all the binary bits in an integer to 1 bits without having to know how many bits are in the integer on the current architecture.
A full example ?. Run this code : (NB: This example is best run in the console and not from within an IDE, since the System.console() method might return null in that case.) import java.io.Console; public class Main { public void passwordExample() { Console console = System.console(); if (console == null) { System.out.println(“Couldn’t get Console … Read more
In the Linux world, masking isn’t usually done with asterisks, normally echoing is just turned off and the terminal displays blanks E.g. if you use su or log into a virtual terminal etc. There is a library function to handle getting passwords, it won’t mask the password with asterisks but will disable echoing of the … Read more
I’ve been wondering this exact same thing. The solution is actually quite simple. Although this is of course quite a modern feature, so you’re stuck to browser compatibility. Webkit can take care of this with a single line of CSS: -webkit-mask-image: -webkit-gradient(linear, left 90%, left bottom, from(rgba(0,0,0,1)), to(rgba(0,0,0,0))) (The new standardised way of doing it … Read more
Finally got the solution while changing mask image and using of Xfermode with Bitmap Mask ImageView mImageView= (ImageView)findViewById(R.id.imageview_id); Bitmap original = BitmapFactory.decodeResource(getResources(),R.drawable.content_image); Bitmap mask = BitmapFactory.decodeResource(getResources(),R.drawable.mask); Bitmap result = Bitmap.createBitmap(mask.getWidth(), mask.getHeight(), Config.ARGB_8888); Canvas mCanvas = new Canvas(result); Paint paint = new Paint(Paint.ANTI_ALIAS_FLAG); paint.setXfermode(new PorterDuffXfermode(PorterDuff.Mode.DST_IN)); mCanvas.drawBitmap(original, 0, 0, null); mCanvas.drawBitmap(mask, 0, 0, paint); paint.setXfermode(null); mImageView.setImageBitmap(result); mImageView.setScaleType(ScaleType.CENTER); … Read more
This function implements the reverse blend described by Mark Ransom, for an additional small but visible improvement: reverseBlend[img_Image, alpha_Image, bgcolor_] := With[ {c = ImageData[img], a = ImageData[alpha] + 0.0001, (* this is to minimize ComplexInfinitys and considerably improve performance *) bc = bgcolor}, ImageClip@ Image[Quiet[(c – bc (1 – a))/a, {Power::infy, Infinity::indet}] /. {ComplexInfinity … Read more
